4 of 5 Please upgrade to USB-C PD and 27500 October 23, 2022
Reviewer: Anonymous Person from USA  
Please upgrade this product to USB-C PD and 27500. 2 USB-A ports, 2 USB-C ports, fast charge/discharge (PD), and using 27500 batteries would be ideal.

5 of 5 Excellent Product February 23, 2022
Reviewer: J from WY United States  
Bought for battery backup/charging for interchangeable 18650’s across another Nitecore flashlight and headlamp. First experience with Nitecore products. Quality is only matched by Nitecore service which was there when I needed it. Also, their humorous product videos ultimately (no joke) convinced me to try their products in the first place, very synergistic experience from start to finish.

Reviewer: Roy M from Edinburg, TX United States  
Being a Computer Tech I thought affordable chargers we a good reason to buy one. When researching Nitecore chargers affordable, quality built and high tech is now the reason to buy now. My family will be purchasing more products for Nitecore. I am also recommending your products to family, friends and all who need reliable chargers.
Thank you

5 of 5 Dual function product March 5, 2021
Reviewer: Kevin from Colorado  
I've had this item for a couple of years now. It had worked great as a regular power bank for all day wrestling tournaments. In addition, it functions as a battery backup for our emergency SRT7 and P12 car flashlights. Really like this product!
